10.861% / 100 = 0.10861
12.428 % / 100 = 0.12428

Answer : The formula of the missing product is, 
Explanation :
The given incomplete equation representing a reaction,
When the sodium metal react with the water then it gives a colorless solution of sodium hydroxide and hydrogen gas. In the solution, sodium hydroxide is present in the form of ions i.e, 
and 
ions.
The balanced chemical reaction will be,
Therefore, the formula of the missing product is,
<span>4.50, 9.00, 36.00
First, count the number of atoms of each element in a single molecule of Mg(ClO4)2.
Mg = 1 atom
Cl = 1 * 2 = 2 atoms
O = 4 * 2 = 8 atoms
Now multiply the number of atoms of each element per molecule of the compound by the number of moles of the compound. So
Mg = 1 * 4.50 = 4.50
Cl = 2 * 4.50 = 9.00
O = 8 * 4.50 = 36.00
So the answer is
4.50, 9.00, 36.00</span>
